People Bar

A new file which is likely related to the upcoming People Bar feature was added. It’s called PeopleBarFlyout.dll and is located in C:\Windows\ShellExperiences.

Settings

We’ve spotted a new item in the Settings app. In the Devices category, the subcategory Pen & Windows Ink was added with one single option to control Windows Ink related app suggestions.

DataStore Cache Dump Tool

A thing that either appears to be included by accident or simply needs to be updated is DataStoreCacheDumpTool.exe

Upon execution you’re greeted with “MICROSOFT INTERNAL ONLY. DO NOT SHARE EXTERNALLY.”

Apps

There were also a few updates and additions to the system apps.

EnvironmentsApp

This is a new app which made its first public appearance in this preview build. Its folder contains files related to Hydrogen and the Havok Physics engine, so it’s most likely Windows Holographic related.

Update: @h0x0d said on Twitter that this app is possibly related to ShareWorld and also linked to a video about it. You can find it below.
